Requirements NIST SOURCE

Require that the following user-installed software execute in a confined physical or virtual machine environment with limited privileges: [user-installed software].

Discussion (NIST Supplemental Guidance)

Organizations identify software that may be of concern regarding its origin or potential for containing malicious code. For this type of software, user installations occur in confined environments of operation to limit or contain damage from malicious code that may be executed.

Engineering Interpretation

No engineering interpretation has been authored for CM-7(6) yet. This section is architected to receive it — see the Requirements and Assessment sections above for the authoritative NIST source content in the meantime.

Assessment

NIST SP 800-53A REV 5.2.0

Assessment Objectives

  1. user-installed software required to be executed in a confined environment is defined;
  2. <CM-07(06)_ODP user-installed software> is required to be executed in a confined physical or virtual machine environment with limited privileges.

Examine

[SELECT FROM: Configuration management policy; procedures addressing least functionality in the system; configuration management plan; system design documentation; system configuration settings and associated documentation; list or record of software required to execute in a confined environment; system component inventory; common secure configuration checklists; system audit records; system security plan; other relevant documents or records].

Interview

[SELECT FROM: Organizational personnel with responsibilities for identifying and/or managing user-installed software and associated privileges; organizational personnel with information security responsibilities; system/network administrators].

Test

[SELECT FROM: Organizational process for identifying user-installed software required to execute in a confined environment; mechanisms supporting and/or implementing the confinement of user-installed software to physical or virtual machine environments; mechanisms supporting and/or implementing privilege limitations on user-installed software].

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for CM-7(6). This section is architected to display, per product: STIG ID, Finding ID, Severity, Title, Description, Check, Fix, CCI, and NIST control mapping — but nothing is populated here until a real DISA STIG/CCI dataset is ingested.
